Understanding Inflation
Inflation occurs when demand for goods and services grows faster than supply, when production costs rise, or when monetary policy increases the money supply too rapidly. It impacts interest rates, wages, savings, and the cost of living.
Central banks use tools like interest rate adjustments and monetary policy tightening to control inflation and maintain price stability.
There are several types of inflation, including demand-pull inflation, cost-push inflation, and built-in inflation.
Types or Variations
Demand-Pull Inflation: Caused by rising demand.
Cost-Push Inflation: Driven by increased production costs.
Built-In Inflation: Linked to wage-price spirals.
Real-World Example
In 2022, many countries experienced high inflation due to supply chain disruptions, rising energy costs, and post-pandemic demand surges.
